To execute the shell:

cmake .
make
./output/main

c++17 required

Theory:

• The basic shell perform these basic operations:

  1. Load config files
  2. Run REPL loop
  3. Clean up memory to prevent leakage.

• In the Loop part following operations are performed:

  1. Read the commands entered by the user.
  2. It will parse the commands so computer can understand the commands.
  3. Execute the commands.
